Frequently Asked Questions
What is the memory capacity and interface of the 24AA32A-I/MS?
The 24AA32A-I/MS provides 32Kbit (4096 bytes) of serial EEPROM storage organized for byte and page write operations via I2C interface. The I2C control byte is 1010DDDR, where the D bits correspond to hardware address pins allowing up to 8 devices on a single I2C bus. The maximum clock frequency is 100 kHz.
What endurance and data retention does the 24AA32A-I/MS offer?
The 24AA32A-I/MS is rated for a minimum of 1,000,000 write/erase cycles per page, ensuring reliable operation in applications with frequent data updates such as event logging or dynamic parameter storage. Data retention is guaranteed for a minimum of 200 years under standard operating conditions, providing extremely stable long-term non-volatile storage.
How many 24AA32A-I/MS devices can share a single I2C bus?
Up to 8 devices of the 24AA32A-I/MS can share a single I2C bus by using the three hardware address pins (A0, A1, A2) to assign unique addresses. The I2C control byte format 1010DDDR allows for independent addressing of each device. This makes it easy to expand non-volatile storage capacity without additional bus interfaces.
What package does the 24AA32A-I/MS use?
The 24AA32A-I/MS comes in an 8-pin MSOP (Mini Small Outline Package), designated JESD-30 code S-PDSO-G8, with manufacturer package code MSOP-8. The MSOP package is significantly smaller than standard SOIC, making it ideal for space-constrained PCB designs in portable electronics, wearables, and compact industrial modules.
Is the 24AA32A-I/MS RoHS compliant and what temperature grade does it support?
Yes, the 24AA32A-I/MS is RoHS compliant with Pbfree Code Yes and JESD-609 Code e3, confirming lead-free construction suitable for environmentally conscious manufacturing. The 'I' in the part number suffix denotes industrial temperature range operation, typically -40°C to +85°C, making it suitable for industrial and outdoor applications.
